Biesak Trail is a Saturday mountain trail race in Kielce, offering 13 km and 26 km distances. It provides runners a concentrated taste of the Świętokrzyskie trails: natural, uneven ground, rapid rhythm shifts, and terrain that challenges steady road pacing.
The 13 km course demands active running from the start, with the finish determined more by leg strength than precise pace management. This distance is suitable for beginners venturing off-road and experienced runners seeking a smaller event that still requires significant effort; now in its 12th edition, the race maintains a close-knit, no-easy-asphalt atmosphere near the regional capital.
